Hi Turns out it's got a lister SR1 engine. I removed the head and gave it a de-Coke, ground in the valves. Bump clearances were wrong. It was on a 20 " piston with no bore wear!!! Runsweet now and starts very easy even in the winter. Replaced the steering box with a Land Rover series three, overhauled the rod / drum brakes and replacecd an oil seal on one of the half shafts. Tin work was shot blasted and repainted. Bit more to do-but these old dumpers are great projects.

You have done a nice job on the restoration. We feel we have the same model but with the SR2 twin cylinder engine in it along with a Newage Coventry 3 speed gearbox. We have no ID tag on the rear panel near where you crank start but have serial numbers of the engine, gearbox and what appears to be a chassis number stamped on a brass tag fixed to the floor area behind the bin.Any clues as to where to look for more info will be greatly appreciated.John
